Description: Anteon is an information technology company that provides services to U.S. government agencies, including the Defense Department, and international clients.

Developments: Anteon became a $1 billion company last year with a boost from its May 2003 acquisition of Information Spectrum Inc. for $90 million—its seventh acquisition in eight years. Information Spectrum provides secure identification cards for military personnel, a market Anteon already served. The firm won several contracts worth more than $100 million last year, including a $105 million job to provide systems engineering and professional services to the U.S. intelligence community. The contract includes adapting computer simulation software for pilots preparing to fly into enemy target areas. But there were also some glitches. Net income in the fourth quarter fell to $5.9 million from $8.6 million after Anteon took a charge on debt refinancing. Upper management got a makeover when Mike Cogburn, the chief operating officer, and Carlton Crenshaw, chief financial officer, both retired. Anteon, which went public the year before last, says it expects to reach about $1.2 billion in revenue this year.
